apply-one-time-script.sh is a CGI helper that, when the file "one-time-script" is present, runs it to rewrite the git-http-backend response. If "one-time-script" generates a response that differs from git-http-backend, the modified response is returned and "one-time-script" is deleted. Requests after the deletion return normal git-http-backend responses. The deletion is not safe under concurrency. The helper serves the modified body first and deletes "one-time-script" only afterward, so a client can issue its next request while the file still exists. Apache runs the CGI for both requests at once, for example when a partial fetch lazily fetches a missing promisor base while the first response is still in flight. Both requests find the file and try to run it; the first deletes it; the second then fails to exec the now-missing file, produces no output, and the server returns HTTP 500: fatal: ... The requested URL returned error: 500 fatal: could not fetch <oid> from promisor remote This is the flaky failure of t5616.47 on the macOS CI runners. Fix it by removing the file with "rm" only after the script has actually changed the response. Because "rm" without "-f" fails once the file is gone, exactly one request removes it and serves the modified body. Any other request serves the unmodified body. Running the script more than once is harmless; only its deletion is serialized, so exactly one request's modified response is ever served. Per-request scratch file names keep concurrent runs from overwriting each other, and no path emits an empty response body. t5616.47 exercises the real code path but, being timing-dependent, passes against the buggy helper almost every time. Add t5567, which drives the helper directly with a fake git-http-backend and forces the overlap with FIFOs; against the pre-fix helper it fails with the same shell error seen in the field: ./one-time-script: No such file or directory Signed-off-by: Michael Montalbo <mmontalbo@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> |

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.adoc
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
